- Waterford NPP is near New Orleans.
- A big flood may be on the way.
- New Orleans has a history with levees not holding (or being made to not hold)
New Orleans Times-Picyaune – (2011) Waterford 3 nuclear plant is not immune to ground-fault concerns, some geologists say
by Richard Thompson
Recent advances in geological study have uncovered an array of deep-seated regional faults, long thought to be dormant, that have shown surface movement throughout southeast Louisiana. And in the wake of Japan’s nuclear crisis, some local geologists and environmental activists are warning that the levees along the Waterford 3 nuclear plant in St. Charles Parish should be evaluated for potential fault hazards. . . .
So levees there are going to hold back this massive flood water that is on the way? We hope.
Recall the flooded Nebraska nuke plant in 2012 – Ft. Calhoun nuclear plant “likely would have melted down” if operators were not forced by NRC to make enhancements before major flooding
NRC Event Number: 51637
Unit 1 –
Event Date: 01/05/2016
Event Time: 22:58 [CST]
SECONDARY CONTAINMENT DECLARED INOPERABLE
“At  CST, on January 5, 2016, with the plant operating at 100 percent power, the main control room alarm indicating high pressure in the auxiliary building actuated. Operators confirmed that the building pressure, corrected for temperature, indicated slightly positive, whereas the building pressure limit in Technical Specifications is 0.0 – 3.0 inches of water negative pressure. Secondary containment was declared inoperable, and the Division 2 standby gas system was started. This action restored building pressure to the acceptable range, and the building was declared operable at [0027 CST] on January 6.
“This condition is being reported in accordance with 10 CFR 50.72(b)(3)(v)(C) as an event that caused the secondary containment to be potentially incapable of performing its safety function. The NRC Senior Resident Inspector was notified.”
